So I made this a while ago. It basically lists all popular/well-known blasters and puts them in their appropriate classes. We've used this system at community wars before, but I decided to make an official topic for it. We've called these classes "light", "medium", and "heavy" or "anything goes". I changed the names a bit for formal purposes (in casual talk it doesn't matter), because size is not the main factor. So it's now "Top-Level", "Mid-Level", and "Low-Level". I also added a "Bottom-Level", which includes squirt-pistol type stuff. Such rounds likely won't be popular, but it's there for completeness, and you could play a round like that indoors, or for novelty or something.

If nobody likes that naming scheme, we could go with numbers (i.e. Level 1, Level 2, etc.) or letters (Class A, Class B, etc.) or something.

I also considered making another tier above all the rest, although it would basically just include the CPS 2000 and maybe the SS 300. That would be assigned "Top-Level", and the class below it would become "High-Level" or something. I decided not to add it for now, because there are really only one or two blasters good enough to be in it. I'm not quite sure about the SS 300, so it would probably go into "Borderline 0" until further testing.

Which brings me to the borderline tiers. Blasters listed here have yet to be sorted, and could be in either class they fall between. They should be tested (by matchup duels) to determine which class they should fall in. Though if some of you have opinions, let us know. I'm not familiar with a lot of blasters on the list, so it may not be perfect yet. A blaster can change classes too, if it ends up being too dominant in its segment.

I really like this and endorse it's use!
